(Sorry that is gonne be 3 post, but I can only add on picture per post.)
I know that both WIFI are on channel 7, because I looked it up in both router, but the app (both, the one from last time, and now a new one) say that they are using a different channel.

For the purble network at the end there is 7(5) and for the orange there is 7(9). These are both mine. Purple is mini router orange/brune is the main router.
